This invention is concerned with wire fabrics methods of making the same and particularly with a means of rendering the ordinary w 'e fabric in ominon use more adaptable to particular uses, a in any case in which it is desired to confine the edges of the wire fabric between a frame and a molding. Accordingly, is proposed to provide, preferably close to the of the selvage of the wire fabric, a stitching of common thread. preferably of some relatively soft and compressible material interlinked with the woof strands of the wire fabric in such a manner that there will be a considerable body of thread above the surface of the wire fabric. It will be readily understood that by so providing the edge of the wire fabric ith a stitching of hread the edges of the wire fabric may be more effectively secured and thereby gripped and clamped between any two surfaces, as wood, for instance, than has been heretofore possible.

It is further proposed to provide visible means to accurately judge the linear dimensions of any required length of the wire fabric as, say, in or yards, without the necessity of resorting to the use of a yard-stick or any other measuring device as has heretofore been necessary. To this end, the stitching alon' at least one edge of the wire fabric is indented at regular intervals of, one foot.

She invention has been fully illustrated in the accompanying drawing, to which reference is to be had in connection with the following detailed description. In the drawing:

1 is a plan view of a section of wire fabric the invention applied thereto,

1g. 2 is an enlarged view of one edge of the fabric shown in Fig. 1, and

Fig. 3 is an edge view of the same.

Referring to Fig. 1 a section of wire fabric comprising interwoven warp and woof a strands a a respectively, is shown as provided close to its selvages a and a with stitchings of common thread 12 and b respectively, as shown more clearly Fig. 2, the thread stitching, as I), being interlinked with the woof strands c of the wire fabric.

Any stitch which will give sufficient height or body to the thread stitching above the surface of the wire fabric may be employed. The stitch should preferably extend above the surface of of the fabric so that a cushioning effect will be obtained. when the fabric is secured between two surfaces. It is, of course, possible to obtain the best cushioning by having the stitching;

extend above each woof strand on each side thereof as is shown in the drawing, especially Fig. 3. The stitching should be more or less linxcd with the strands of fabric which extend argularly thereto, whether they be woof or warp, for the stitching may be used across the ends of a piece of fabric as well as along the selvage. In the illustrated embodiment the angle of the woof strands to the fabric stitching is 90. A chain-stitch has been illustrated in the drawing but any other stitch, such as a lock-stitch or a chain-lock stitch would be satisfactory and such stitches may be made by sewing machine action or by knitting, or by hand, or any other way as desired.

In order to provide visual means to determine any required length of the wire fabric the stitching along one edge may be indented at regular intervals of, say, one foot as shown at 12 b in Fig. 1 to form suitable stitched markers. It will be obvious that the stitching along both selvages may be so indented if desired thus facilitating the cutting of the same square with a longitudinal parallel edge thereof.

The links of the stitching have been illustrated in the drawing as disposed at regular intervais progressively with respect to the woof strands of the wire fabric but it is not necessary that such be the case. The effectiveness of the product will not be impaired by any irregulariin the links of the stitching with respect to the woof strands of the wire fabric.

It will thus be seen that there has been provided a wire fabric which is rendered more effective in use by the application along the selvages thereof of thread stitchings which project above the surface of the fabric and that, by providing indentations of the stitching at regular intervals along at least one selvage of the fa ric, a highly convenient means of determining any required length of fabric has been supplied. Wire fabric manufactured With the improvements disclosed herein is, as has been highly effective; it may be produced at very little additional cost; and in fact the utmost simplicity has been retained throughout.

It is to be understood that while the invention has been described with reference to a pr fer-red embodiment in which the stitching is positioned close to the selvage of the wire fabric, wire fabric provided with stitching at any distance from the selvage is included in its purview. In fact, no limitation upon the scope ill or spirit of the invention is intended except as indicated in the following claims.

What I claim is:

1. As an article of manufacture, a wire fabric having fiber stitching interlinked with the strands of the fabric, said stitching being close to the selvage of the fabric and projecting above the surface thereof and indented at regular intervals.

2. As an article of manufacture, a Wire fabric having fiber stitching interlinked with the Woof strands of the fabric, said stitching being close to the selvage of the fabric and evenly spaced from the selvage, and projecting above the surface of the fabric and indented at regular intervals.

3. A screen fabric formed of metal wire and having a mesh adapting it for use for screening purposes and provided along the parallel side edges thereof with sewing-machine stitches forming friction-gripped cushioned edges adapting the fabric to be effectively gripped and clamped along such edges.

a. A screen fabric formed of metal Wire and having a mesh adapting it for use for screening purposes and provided along the parallel side edges thereof with sewing-machine stitches of relatively soft compressible material forming friction-gripped cushioned edges adapting the fabric to be efiectively gripped and clamped along such edges.

5. A screen fabric formed of metal wire and having a mesh adapting it for use for screening purposes and provided along the parallel side edges thereof with looped threads of a material different from that of which the body of the fabric is formed forming friction-gripped cushioned edges adapting the fabric to be effectively gripped and clamped along such edges. 6. A screen fabric formed of metal wire and having a mesh adapting it for use for screening purposes and provided along the parallel side edges thereof with sewing-1nachine stitches passing between and around the woof wires of the fabric forming friction-gripped cushioned edges adapting the fabric to be effectively gripped and clamped along such edges.
